Application filed October 29, 1923. Serial'No. 671,468. I i t To all whom it may concern; I

Be it known that I, OsoAaM. Hosrroma Bearings, of which the following is'a specificatlon.

The present invention relates generally to,

thrust bearings and more particularly to a thrust bearing fortlie crank shaft of Ford automobiles and tractors. v.

It is well knownthatiin automobiles of this type, that considerable trouble arises from faulty ignition caused by endwise play of the crank shaft due to wear of its bearings. This end play causes the magneto to generate an unsteady current of electricity or none at all, which causes the engine to miss fire, and one object of my invention is to prevent such endwise play of the crank shaft in an old machine when its bearings have become worn, so that the magneto will have full, steady power, and the motor will run smoothly and with more power, and the life of the motor will be prolonged. i

A further object of the invention is to provide a device which is inexpensive to' manufacture, that may readily be attached to an engine in a few minutes by the simple use of an ordinary wrench, and that will be found to be reliable for the purpose intended.

lVith the above general objects, in view, the invention consists essentially in the construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which Figure 1 represents a side view, parts being broken away, of my invention applied.

Figure 2 is a front view of the same appliec Figure 3 is a front view showing the device detached, the ad ust1ng screw or bolt being removed.

Figure 4 is a side vie similar to Fig.1,

of a modified form.

Figure 5 is a section on line 5-5 of Fig. 4. Similar reference characters designate corresponding parts throughoutthe several figures of the drawing.

Referring to these figures, A, indicates the timing gear housing of a Ford motor through which the forward portion of the crank shaft B, has hearing at C. The crank shaft projects forward beyond the timing gear housing and receives the lower fanzbelt pulley l),*-upo n which the fan belt E, runs. F, is the connecting pm, which is used to cooperate with the usual startingcrank.

1 My improved. thrust bearing is, preferably made of 'any suitable metal, and compr1ses a main; body portion 1, widened at the lower end and having a notch or opening 2,

adapted to beslipped sidewise onto, the crank shaft. raised portion 3, providing asrnooth face4,

Bordering the notch 2, is attached a forming a bearing surface for the end of the hub D, of pulley D.

At the end opposite the notch 2, the body of the device has a narrowed end which is curved backward at 5 to form an attaching portion 5, the latter portion being provided with an opening 6, and the body 1,

with an enlarged opening 7. The body is also provided with boss 8, having a threaded opening 8 theretln'ougl'i, and through which a screw or bolt 9, isscrewed. Surrounding this bolt is a coil spring 11 one end of which bears against the body 1, and the other end against the head 10, of the bolt in order to prevent the bolt from unscrew ing from its adjusted position.

My improved thrust bearing is installed as follows :The small stud bolt just above the front of the housing A, with sufficient force to eliminate all longitudinal play in the crank shaft, but not tight enough to cause heating of the bearing; M

Figures 4 and 5 show a modified form bent as at 5". The boss 8 is a separate piece riveted on body 1 as shown 111 Fig. 5. Instead of a spring, a lock nut 11 s used. In

. both forms shown in Figs. 1 aud t, either a spring 11 or a lock nut 11 may be used.

My invention will be found to be easily and readily installed, and to bring about highly satisfactory results in causing the motor to run steadily and smoothly without misfiring. It also renders the motor easy to start, owing to the fact that the magnets and coils are in proper spaced relation necessary to get the best possible results.

From the foregoing description it will be obvious that my inventionprovides a simple,

efiective, and :reliable thrust bearing, and one that will appeal to Ford owners.

I claim 1. A device of the class described, comprising a'main body portion tapered on one side to form a narrowed upper end, the lower end being provided with a notch having a semicircular end adapted to fit over the for- .wardend of the crank shaft of a Ford motor betweenthe fan belt pulley and the tim ing ygear housing, the upper end being curved rearwardly and provided with abolt opening, and an adjusting bolt threaded through the body port-ion and adapted to be screwed against the front ofisaidhousing,

fort-he purpose specified.

2. A device of the class described, comprising a. main body portion, the lower end being provided with an open ended notch adapted to fit over the forward .end of the crank shaft of a Ford motor betweenthe fan belt pulleyaandithe timing gear housing, the upper end being provided with means adapted to be attached to the timing gear housing, and thrust means intermediate the notch and the attaching end, adapted to engage the timing gear housing to cause the notched end to thrust against the pulley.

3. A device of the class described, comprising a main body portion, the lower end being provided with an open ended notch land adjustable thrust means intermediate the notch and the attaching-end, adapted to engagethe'timing gear housing to cause the notched end to thrust against the pulley.
